In Australia the size of many bodies of water are referenced back to the size of Sydney Harbour, that is a body of water x is y times the size of the Sydney Harbour. For example:


 * Lake Argyle, the Ord river dam and Australia's largest lake, is variously described as "18 times that of Sydney Harbour",  "8-13 times the size the volume of Sydney Harbour." , and "nine times the size of Sydney Harbour".


 * Warragamba Dam in New South Wales and Sydney's major water supply is described as being "4 times the size of Sydney Harbour".


 * Lake Eucumbene, one of the major dams in the Snowy Mountains Scheme, "holds nine times the volume of Sydney Harbour", or perhaps thirteen times.


 * Lake Hume is six times the size of Sydney Harbour

The comparison is not confined to dams.


 * Jervis Bay in New South Wales is "at least 6 times bigger in volume (and 4 times bigger in area) than Sydney Harbour" ; and


 * Boston Bay in South Australia, on which Port Lincoln is located, is three and a half times larger than Sydney Harbour.
